  • Patent number: 10663279
    Abstract: Metal film thickness can be determined using the sheet resistance, resistivity, and temperature coefficient of resistivity for the metal film. Variation in film thickness measurements caused by resistivity can be reduced or eliminated. A probe head may be used for some of the measurements of the metal film. The probe head can include a temperature sensor used during sheet resistance measurements. A wafer on a chuck is heated, such as using the chuck or the probe head, for the measurements.

  • Patent number: 7908475
    Abstract: Session Inter-Device (SID) mobility networks (50, 100, 150) are described in which a seamless transfer of a communication session from a first device (56, 106, 116) to a second device (66, 116, 166) can be achieved without interrupting the active session. According to the SID mobility network (50), the transfer can be accomplished by transferring away from the Transferring Node or first device (56) the IP address associated with the active session (58) so that the network (50) will route the session to the desired Target Node or second device (66). The Transferring Node (56) transfers its IP address (58) to the Agent (60) and stops requesting data packets addressed to its IP address (58). The Agent (60) then begins to request and eventually receive the packets addressed to the Transferring Node's IP address (58). The Agent (60) then transfers the packets to the Target Node (66).

  • Publication number: 20090161850
    Abstract: A method, event information processing system, and wireless communication system capture call/session event information. A series of call/session event information sets (128) is received. Each call/session event information set is classified into one of a normal behavior equivalence category and an abnormal behavior equivalence category. An individual call/session event record (126) is created for each event associated with an abnormal behavior equivalence category. The individual call/session event record (126) is inserted into a call/session event record buffer (124). At least two consecutive call/session events associated with a normal behavior equivalence category are determined to have occurred. A single call/session event record (126) for the at least two consecutive call/session events associated with a normal behavior equivalence category is created.

  • Publication number: 20070119927
    Abstract: A tag mounting device can temporarily mount a tag transmitter on a shipping container or trailer for tracking location of the shipping container or trailer. The tag mounting device includes a mounting frame having a support leg with opposing ends. A clamp mechanism is carried by the support leg for clamping the support leg onto a rim of a container or trailer such that the support leg extends against a surface of the container or trailer. A tag support member extends outward from the support leg. A tag transmitter is carried by the tag support member and operative for transmitting wireless signals to at least one receiver for subsequent processing to determine the location of the tag transmitter and a container or trailer on which the tag mounting device is mounted.

  • Publication number: 20060203850
    Abstract: An Access Point (AP) receives a first set of timing information comprising timing information for at least one neighboring AP and conveys, to a user equipment (UE), a second set of timing information comprising timing information for the at least one neighboring AP, wherein the second set of timing information is derived from the first set of timing information. Based on the second set of timing information, the UE is able to determine a time to scan the at least one neighboring AP. In various embodiments of the present invention, the AP may receive the first set of timing information from another UE or may receive the timing information without the involvement of the another UE, for example, via a network interconnecting the APs or by monitoring an air interface of the at least one neighboring AP.

  • Publication number: 20050092031
    Abstract: This invention involves apparatus and methods for making fibers by passing a molten material like glass, polymer, etc. through orifices or tips in a fiberizing bushing and then cooling the molten material coming from the tips and newly formed fibers with a cooling apparatus. The cooling apparatus is made from a metal to withstand the environment close beneath a fiberizing bushing and to provide the needed thermal conductivity to carry heat away rapidly. Alloys comprising nickel and titanium and that are in a martensite structure below about 200 degrees F. are used for at least parts of the cooling apparatus to reduce cost and/or provide for improved life and cooling performance and/or to improve fiberizing efficiency.
